The MCL-FK is a butterfly valve for shutting off or regulating flow, with structural characteristics that make it ideal for industrial applications requiring high performance and long-term reliability. This valve is also equipped with the customisable Labelling System.
BUTTERFLY VALVE
• Interchangeable Disk in PVDF with through shaft, available in differentthermoplastic materials: PVC-U, PP-H, PVC-C, ABS
• Overall dimensions of the valve in accordance with standard ISO 5752(DN 40÷200 Medium Series 25, DN 250÷ 300 Long Series 16) and DIN3202 K2 and ISO 5752 (DN 65÷200 K2, DN 250÷300 K3)
• Can also be installed as an end line valve, bottom discharge valve or tankdump valve
• Special Lug version PN 10 fully drilled according to DIN 2501 or ANSIB16.5 cl.150 with molded-in AISI 316 stainless steel threaded inserts
• Possibility of installing a manual reducer or pneumatic and/or electric ac-tuators by applying an ISO standard drilling PP-GR flanges. DN 40 ÷ 200valve equipped with plate with rack in PP-GR. For actuated versions withflange drilled according to ISO 5211 F05, F07, F10. DN 250÷300 valve,fitted with one-piece top flange in high mechanical strength PP-GR withmounting flange for internal components drilled according to standardISO 5211 F10 (excluding DN 350÷400), F12, F14.

1 Ergonomic handle in HIPVCequipped with locking and unlocking device, release, quick operation and graduated adjustment in 10 intermediate positions (DN 40÷200). The operating range, starting from the first few degrees of valve opening, also guarantees extremely low pressure drops
2 Customisable LabellingSystem: integrated module in the handle, made of a transparent protection plug and a customisable tag holder using the LSE set (available as an accessory). The customisation lets you identify the valve on the system according to specific needs
3 STAINLESS steel square sectionstem completely isolated form the fluid complying with standard ISO 5211: DN 40÷65: 11 mmDN 80÷100: 14 mmDN 125÷150: 17 mmDN 200: 22 mmDN 250÷400: 27 mm
4 Body in polypropylene basedcompound reinforced with fibreglass (PP-GR) resistant to UV rays and characterised by high mechanical strength.
5 Drilling pattern using ovalslots that allow coupling to flanges according to numerous international standards. The
special self-centring inserts in ABS supplied for DN 40÷200 guarantee the correct axial alignment of the valve during installation.For DN 250÷400 valves, the drilling pattern for the self-centring system is of the traditional type according to DIN and ANSI standards
6 Interchangeable liner withthe dual function of forming a hydraulic seal and isolating the body from the fluid

TECHNICAL DATA
KV100 FLOW COEFFICIENTThe Kv100 flow coefficient is the Q flow of litres per minute of water at a temperature of 20°C that will generate ∆p= 1 bar pressure drop at a certain valve position.The Kv100 values shown in the table are calculated with the valve completely open.

Actuator mounting flangeThe valve can be equipped with standard pneumatic or electric actuators and gearbox for heavy-duty operations, using a flange in PP-GR reproducing the drilling pattern pro-vided for by standard ISO 5211.
CUSTOMISATIONThe FK valve is equipped with the customisable Labelling System.This system lets you create special labels to insert in the handle. This makes it extremely easy to apply company logos, identification serial numbers or service indications such as, for example, the valve function in the system, the transported fluid, but also specific information for customer service, such as the customer name or installation date or location on the valves.The specific LCE module is a standard supply and is made up of a rigid transparent water-resistant PVC plug (A-C) and white tag holder (B) made of the same material, one side of which bears the FIP logo (fig. 1).The tag holder, inserted in the plug, can be removed and, once overturned, used for customisation by applying labels printed with the software supplied with the LSE set. Proceed as follows to apply the label on the valve:1) Remove the upper part of the transparent plug (A) rotating it counter-clockwise
as indicated by the word "Open" on the plug and remove it.2) Extract the tag holder from its housing on the lower part of the plug (C)3) Apply the adhesive label on the holder (B) to align the profiles matching the tab
position.4) Reinsert the tag holder in its housing at the bottom of the plug.5) Reposition the top of the plug in the housing rotating it clockwise; this way the
label is protected against the elements.

POSITIONING THE VALVEPosition the valve between two flanged stubs, taking care to respect the installation tolerances Z. It is advisable to always install the valve with the disk partially closed (it must not exit the body) and avoid any misalignment of the flanges, as this would cause leaks.Where possible comply with the following requirements: - Conveying dirty fluids: position the valve with the stem inclined at an angle of 45° to the pipe support plane.- Conveying fluids with sediment: position the valve with the stem parallel to the pipe support plane.- Conveying clean fluids: position the valve with the stem perpendicular to the pipe support plane.
106
TIGHTENING THE STUD-BOLTSBefore tightening the stud-bolts, it is advisable to open the disk in order to prevent damage to the seal. Tighten the stud-bolts in a uniform manner, in the order indicated in the figure, to the nominal operating torque value indicated in the table. The stud-bolts do not need to be excessively tightened in order to produce a perfect hydraulic seal. Overtightening could adversely affect the operating torque of the valve.
* Tightening torques for nuts and bolts on couplings with backing rings.Values required to obtain the hydraulic test seal (1.5xPN at 20°C) (new or lubricated nuts and bolts)

HANDLE LOCKThanks to the multifunctional handle and the red manoeuvre button on the lever, you can perform a 0°-90° operation and a graduated operation by means of the 10 inter-mediate positions and a stop lock: the handle can be locked in each of the 10 positions by simply pressing the Free-lock button. A lock can also be installed on the handle to protect the system against tampering.
The valve is two-way and can be installed in any position. It can also be installed at end line or tank.
FREE LOCK
WARNINGSMake sure that the valves installed on the system are suitably supported for their weight.
Always avoid sudden closing manoeuvres and protect the valve from accidental opera-tions. To this end, it is advisable to install a reduction gear, available on request.
In the case of conveying dirty fluids or those with sediments, install the valve inclined as shown in the figure.
